Definitions

  • the present invention relates in general to a rear-signalling light for motor vehicles and in particular to the so-called “third-stop light", i.e., the light which is set at the rear top centre of the vehicle.
  • lights of the aforementioned type which normally comprise: a lamp-holder base; a printed circuit; a plastic body having a reflecting dish shape, which is normally referred to in technical terms as “reflecting dish”, with an aluminizing treatment on the inside designed to direct the light beam; a variable number of lamp-bulbs, in general of the 5-Watt "W 5 W” type, inserted and fixed in the reflecting dish; and a coloured lens, generally red, which covers the compartment delimited by the aforesaid reflecting dish.
  • the purpose of the light is to signal slowing-down of the motor vehicle in a way that is more visible from a distance as compared to the stop lights positioned low down at the two sides of the motor vehicle.
  • the above type of light which uses very small lamp-bulbs, has also a reflecting dish of dimensions that are contained and in any way appropriate to the brightness of the lamp-bulb.
  • the purpose of the present invention is to provide a light which will enable a simple and economically advantageous process of fabrication for depositing the atoms of aluminium on the reflecting dish and which at the same time will preserve the contained dimensions which are optimal for low-power lamp-bulbs.
  • Said support is designed to be inserted by snap action, or another equivalent system, in a seat 5 made on a component element 7, which is formed by a base 8 and a surface shaped so as to identify a set of half-dishes arranged in a row alongside one another.
  • the component element 7 is obtained by moulding in two symmetrical half-shells 12 and 13, which are divided substantially along a plane passing through the axes of symmetry of the reflecting dishes that said half-shells form when they are joined together.
  • the two half-shells are kept joined by machining bands or strips 14, set on their bottom edge, which can then be discarded at the moment of assembly of the light.
  • the base 15 of the component element 7 is made of a single piece, whereas the reflecting dishes 11 are formed by two half-shells 17 and 18 joined together at the base by thin-film hinges 19, which enable rotation of the half-shells with respect to the base.
  • the reflecting dishes will have an appropriate shape in such a way that the lamp-bulb or the LED can be set in the desired position in order to transmit the beam of light in a suitable way.
  • the component element 7 is then inserted, in the step of assembly of the light, in a shell 20 provided with attachments 21 for mounting it on the motor vehicle.
  • the shell is provided on its front part with a coloured lens 22, generally red, which hermetically seals the shell 20.
  • the reflecting dishes of the component element 7 are made of two symmetrical half-shells, in such a way that the aluminizing operation inside the reflecting dishes, which is necessary for providing brightness to the light, can be performed automatically with an operation that is much simpler and with qualitatively excellent results as compared to that for a closed reflecting dish.
  • the two half-shells are joined together and secured in this position, for example by means of rivets or snap-action hooks 23 or equivalent anchoring means, distributed throughout the length of the component element.
  • the above embodiment of the reflecting dishes of the light in addition to facilitating the aluminizing process, enables reflecting dishes of reduced dimensions to be obtained, with optimized profiles which improve the efficiency of the light beam.
